Measurement of Calcium by Ion Selective Electrode (CAT#: STEM-ACT-0101-WXH)

Introduction

Calcium, the most abundant mineral in the body, is found in some foods, added to others, present in some medicines (such as antacids), and available as a dietary supplement. Calcium makes up much of the structure of bones and teeth and allows normal bodily movement by keeping tissue rigid, strong, and flexible <br />The normal regulation of calcium in our blood stream is similar to the way a thermostat works. The body is set to have a normal amount of calcium (somewhere between 8.6 to 10.3 mg/dL). The parathyroid glands can be thought of as the “calcium thermostat” of the body.




Principle

An ideal ion-selective electrode (I.S.E.) consists of a thin membrane across which only the intended ion can be transported. The transport of ions from a high conc. to a low one through a selective binding with some sites within the membrane creates a potential difference.

Applications

• Used for the potentiometric determination of several anions (fluoride, chloride, bromide, iodide ion) and cations (sodium, potassium, calcium ion).
• Used for endpoint detection in potentiometric titration.
• In biochemistry, ion selective electrodes are used for the determination of enzymes and substances which interact with enzymes.

Procedure

1. Preparation of Standards
2. Instrument Setup and Operation
3. Analysis of sample
